Abstract

La présente invention concerne un transformateur de mode qui permet un couplage avec affaiblissement faible entre les modes optiques de deux guides d'ondes aux différences d'indice dissemblables. La taille du mode et l'indice effectif sont graduellement modifiés entre les deux guides d'ondes de manière que la forme, la taille et la vitesse du mode sont progressivement transformés avec une perte de puissance minimale. Le transformateur de mode de l'invention permet de coupler le mode d'un guide d'ondes à fibres optiques à faible différence d'indice au mode d'un guide d'ondes planaire à différence d'indice élevée et vice-versa.
